Filing dispute for overdue university tuition
So, here's the story: I attended a summer program at a university and paid for it with a loan I was approved for through the school's financial services. Nine months (!) after I completed the program, I received a bill from a collection agency saying that the tuition had never been paid. As it turned out, it indeed hadn't been. The university did not approve receipt of the loan because the particular loan I was originally granted was intended only for full time students, not summer students like me. So I contacted the university and they basically said I'd have to get a loan elsewhere. Well, it took me another 4 months to get approved for another loan because I didn't have a cosigner, and I paid the university as soon I as I got it. So, this shows up on my credit report now, once as being 120 days overdue from July-November, and a second time showing 120 days overdue from November only, and then OK in December and January. Honestly, the first one is correct, but I'd much rather have the 120 days show up for one month rather than seven. Of course, I'd rather have it not show up at all because I did everything I could and would not have attended the program to begin with if I knew paying for it was going to be such a huge hassle. So, my question: is this the kind of thing I can dispute? At the very least I'd prefer it to show up only once, but can I get it to not show up at all, provided I write to the university (to summarize the situation) along with the credit bureau (Experian)? My credit scores are 757/748/651, with the latter score being the one affected by this, so I'd really like to do something about it if possible.
